In this example, the insertion member main body 333 and the lower end member 334 are both square pipes having a square cross section. The thickness of the lower end member 334 is the same as the thickness of the fixed plate 323.

  A pair of slits 335 are provided as insertion holes at the boundary between the insertion member main body 333 and the lower end member 334. The pair of slits 335 penetrates the insertion member 331 in a direction orthogonal to the axis of the insertion member 331. In addition, the pair of slits 335 are formed in the insertion member 331 by providing a notch on the lower end surface of the insertion member main body 333. The pair of slits 335 are respectively provided at the positions of two sides facing each other among the four sides of the square that is the outer cross-sectional shape of the insertion member 331.

  The device receiving plate 332 is fixed to the upper end surface of the insertion member 331. The device receiving plate 332 is provided with a plurality of bolt through holes 332a. In this example, bolt through holes 332a are provided at the four corners of the rectangular device receiving plate 332, respectively. In this example, when the upper support base 33 is viewed along the axis of the insertion member 331, each side of the square that is the outer shape of the insertion member 331 is replaced with each side of the rectangle that is the shape of the device receiving plate 332. The insertion member 331 is fixed to the device receiving plate 332 with an inclination of 45 °. The car shock absorber 21 is fixed to the upper surface of the device receiving plate 332.

  As shown in FIGS. 2 and 3, the holder 34 includes a plurality of insertion plates 341 that are holding members inserted into the pair of slits 335, and a plurality of (in this example, fastening plate 341 and fixing plate 323). 2) holding bolts 342 which are fasteners.

  The insertion plate 341 is inserted across a pair of slits 335. Thereby, the insertion plate 341 penetrates the insertion member 331 in a state where one end and the other end of the insertion plate 341 are exposed to the outside of the insertion member 331. Bolt through holes 341a are provided at one end and the other end of the insertion plate 341, respectively. The position of each bolt through hole 341a is a position that individually overlaps with a pair of bolt holes 323a located at the diagonal of the fixing plate 323.

  The insertion plate 341 is fixed to the fixing plate 323 by attaching the holding bolt 342 passed through the bolt through hole 341 a to the bolt hole 323 a of the fixing plate 323. Thereby, the state where the insertion member 331 is placed on the placement surface 322a of the housing member 322 is maintained.

  The state of the shock absorber support device 31 includes an extended state in which the insertion member 331 is placed on the mounting surface 322a of the housing member 322, and a shortened state in which the insertion member 331 is inserted into the insertion hole 324. Can be changed between. The height dimension of the shock absorber support device 31 from the pit surface 20 is larger when the shock absorber support device 31 is in the extended state than when the shock absorber support device 31 is in the shortened state.

  FIG. 6 is a side view showing the shock absorber support device 31 of FIG. FIG. 7 is a cross-sectional view taken along the line VII-VII in FIG. In this example, the length of the diagonal of the square that is the outer cross-sectional shape of the insertion member 311 is substantially the same as the diameter of the open hole 325. Further, in this example, the length of the square diagonal line that is the outer cross-sectional shape of the insertion member 311 is one side of the square that is the shape of the opening of the insertion hole 324 when viewed along the depth direction of the insertion hole 324. And the length of the square diagonal of the opening of the insertion hole 324 is shorter.

  In a state where the insertion member 331 is placed on the mounting surface 322a, when the insertion member 331 is viewed along the depth direction of the insertion hole 324, a part of the insertion member 331 serves as a hook portion of the opening portion of the insertion hole 324. The insertion member 331 is partly removed from the position that protrudes from the region and fits in the region of the opening of the insertion hole 324. The insertion member 331 is supported by the housing member 322 by placing the hook portion of the insertion member 331 on the placement surface 322a.

  In this example, as shown in FIG. 7, when viewed along the depth direction of the insertion hole 324, the corners of the four corners of the square, which is the outer cross-sectional shape of the insertion member 331, are the shape of the opening of the insertion hole 324. By shifting in the circumferential direction with respect to the four corners of a certain square, the square corners of the insertion member 331 protrude from the region of the opening of the insertion hole 324 as a hooking portion, and the four hooking portions of the insertion member 331 become the housing member 322. Are mounted on the mounting surface 322a.

  Further, in this example, when viewed along the depth direction of the insertion hole 324, the corners of the four corners of the square, which is the outer cross-sectional shape of the insertion member 331, are aligned with the four corners of the square of the opening of the insertion hole 324 and the circumferential direction. By matching, the insertion member 331 fits in the region of the opening of the insertion hole 324, and the insertion member 331 can be inserted into the insertion hole 324. The shock absorber support device 31 is shortened by inserting the insertion member 331 into the insertion hole 324.

  Next, a height adjustment method for adjusting the shock absorber support device 31 from the extended state to the shortened state will be described. During normal operation of the elevator, the car shock absorber 21 is supported by the shock absorber support device 31, and the shock absorber support device 31 is in the extended state. When the shock absorber support device 31 is in the extended state, the hooking portion of the insertion member 331 is placed on the mounting surface 322 a of the housing member 322, and this state is maintained by the holder 34.

  Further, when the maintenance worker performs maintenance work on the elevator, the car 6 may be moved to a position lower than the stop position on the lowest floor of the car 6. In this case, the shock absorber support device 31 is adjusted from the extended state to the shortened state, and the height position of the car shock absorber 21 is lowered.

  FIGS. 8-10 is a perspective view for demonstrating the height adjustment method of the buffer support device 31 of FIG. That is, FIG. 8 is a perspective view showing a state in which the holder 34 is removed from the lower support base 32 and the upper support base 33 of FIG. FIG. 9 is a perspective view showing a state where the insertion member 331 is displaced to a position where it can be inserted into the insertion hole 324 of FIG. Further, FIG. 10 is a perspective view showing a state where the insertion member 331 of FIG. 9 is inserted into the insertion hole 324.

  When adjusting the shock absorber support device 31 from the extended state to the shortened state, first, each holding bolt 342 is removed from the bolt hole 323a of the fixing plate 323, and then the insertion plate 341 is removed from the slit 335. Accordingly, as shown in FIG. 8, the holder 34 is detached from the lower support base 32 and the upper support base 33, and the upper support base 33 can be displaced on the mounting surface 322 a of the accommodation member 322.

  Thereafter, the insertion member 331 is displaced on the mounting surface 322a from the state where the insertion member 331 is mounted on the mounting surface 322a of the housing member 322 while the car shock absorber 21 is attached to the upper support base 33. 9, the insertion member 331 is displaced to a position where it can be inserted into the insertion hole 324. At this time, since the insertion member 331 is guided by the inner peripheral surface of the opening hole 325, the hooking portion of the insertion member 331 is difficult to come off from the mounting surface 322a.

  Thereafter, when the insertion member 331 reaches a position where it can be inserted into the insertion hole 324, the insertion member 331 passes through the opening of the insertion hole 324 by its own weight as shown in FIG. Inserted into. Thereby, the height dimension from the pit surface 20 of the shock absorber support device 31 is shortened, and the state of the shock absorber support device 31 is shortened.

  FIG. 11 is a side view showing the shock absorber support device 31 of FIG. 12 is a cross-sectional view taken along line XII-XII in FIG. When the shock absorber support device 31 is in the shortened state, the insertion member 331 is within the region of the opening of the insertion hole 324 when viewed along the depth direction of the insertion hole 324. Further, when the shock absorber support device 31 is in the shortened state, the device receiving plate 332 overlaps the upper surface of the fixed plate 323.

  That is, when the lower support base 32 and the upper support base 33 are viewed along the depth direction of the insertion hole 324, a part of the insertion member 331 protrudes from the region of the opening of the insertion hole 324 as shown in FIG. When the outer cross-sectional shape of the insertion member 331 is in the state shown in FIG.

  The procedure for adjusting the shock absorber support device 31 from the shortened state to the extended state is the reverse of the above procedure.

  13 shows the height position of the car shock absorber 21 when the shock absorber support device 31 of FIG. 6 is in the extended state, and the car shock absorber when the shock absorber support device 31 of FIG. 11 is in the shortened state. FIG. 13A is a comparison view comparing the height position of the container 21, FIG. 13A is a view showing the car shock absorber 21 when the shock absorber support device 31 is in an extended state, and FIG. 13B is a shock absorber. It is a figure which shows the cage | basket buffer 21 when the container support apparatus 31 is a shortened state.

  The lower support base 32 is fixed to the pit surface 20 by a plurality of (four in this example) bolts 41 respectively passed through the bolt through holes 321a of the seat plate 321. The car shock absorber 21 is fixed to the upper support 33 by a plurality of (four in this example) fasteners 42. Each fastener 42 has a bolt passed through the bolt through hole 332a of the device receiving plate 332 and a nut attached to the bolt. Each fastener 42 fixes the car shock absorber 21 to the device receiving plate 332 by collectively fastening the lower portion of the car shock absorber 21 and the device receiving plate 332 between the bolt head and the nut of the fastener 42. doing.

  As shown in FIG. 13, the height position of the car shock absorber 21 from the pit surface 20 is such that the shock absorber support device 31 is in an extended state (FIG. 13 (a)) and a shortened state (FIG. 13 (b)). The amount of adjustment is adjusted by the adjustment amount h. The adjustment amount h is determined by the insertion amount of the insertion member 331 into the insertion hole 324.

  Next, an operation method during maintenance inspection will be described. FIG. 14 is a side view showing a state where the car 6 of FIG. 1 is stopped on the lowest floor. When the car 6 is stopped at the lowest floor, the car 6 is separated from the car shock absorber 21 upward.

  For example, when performing maintenance and inspection work on the first car door opening / closing device 9, if the car 6 is stopped at the lowest floor, the first car door opening / closing device 9 is moved to the first position as shown in FIG. Since it faces the landing door opening / closing device 16, maintenance inspection of the first car door opening / closing device 9 cannot be performed from the landing 13 on the lowest floor. In order to perform maintenance and inspection work on the first car door opening / closing device 9, the car 6 is moved further downward than the stop position on the lowest floor, and the first car door opening / closing device 9 is moved to the first landing doorway. It is possible to expose from 14 to the hall 13 on the lowest floor.

  FIG. 15 is a side view showing a state in which the car 6 of FIG. 14 is moved further downward than the lowest floor. When the car 6 is moved further down from the lowest floor while the shock absorber support device 31 is in the extended state, as shown in FIG. 15, all of the first car door opening / closing devices 9 become the first landing doorway. The car 6 is placed on the car shock absorber 21 before being exposed to 14, and the car 6 cannot be moved further downward. Therefore, if the shock absorber support device 31 is kept in the extended state, the entire first car door opening / closing device 9 cannot be exposed from the first landing doorway 14, and the first car door opening / closing device 9 cannot be exposed. The maintenance inspection work cannot be performed on the portion A hidden by the landing door opening / closing device 16 of No. 1.

  Therefore, in the present embodiment, the shock absorber support device 31 is adjusted from the extended state to the shortened state so that the height position of the car shock absorber 21 from the pit surface 20 is lowered, and then the car 6 is moved from the lowest floor. Move further downward.

  FIG. 16 is a side view showing a state in which the car 6 is moved further down than the lowest floor in a state where the shock absorber support device 31 of FIG. 15 is adjusted to the shortened state. After the shock absorber support device 31 is adjusted from the extended state to the shortened state, when the car 6 is moved further downward than the lowest floor, as shown in FIG. It is exposed from the first hall entrance 14 to the lowermost hall 13. Thereafter, the lower surface of the car 6 is placed on the car shock absorber 21 while the entire first car door opening / closing device 9 is exposed from the first landing doorway 14. Thereafter, with the lower surface of the car 6 placed on the car shock absorber 21, maintenance and inspection work for the first car door opening / closing device 9 is performed from the landing 13 on the lowest floor.

  In the elevator shock absorber support device 31 and the height adjustment method of the shock absorber support device 31, a mounting surface 322 a on which the insertion member 331 of the upper support base 33 is placed is formed on the housing member 322 of the lower support base 32 and inserted. An insertion hole 324 into which the member 331 can be inserted is provided in the housing member 322, and the insertion member 331 can be inserted into the insertion hole 324 through the opening of the insertion hole 324 formed in the mounting surface 322a. By moving the member 331 on the mounting surface 322 a of the housing member 322, the insertion member 331 can be inserted into the insertion hole 324. Thus, even when the car shock absorber 21 is placed on the upper support base 33, the insertion member 331 can be moved while the load of the upper support base 33 is supported by the mounting surface 322a. Therefore, the height dimension of the shock absorber support device 31 can be easily adjusted, and the labor for adjusting the height position of the car shock absorber 21 can be reduced. Moreover, each shape of the lower support stand 32 and the upper support stand 33 can be made into a simple shape, and the effort of manufacturing the shock absorber support device 31 can also be reduced.

  In addition, a fixing plate 323 provided with an open hole 325 is fixed to the mounting surface 322a of the housing member 322, and the insertion member 331 is mounted on a portion of the mounting surface 322a exposed in the open hole 325. Therefore, the range in which the insertion member 331 is displaced can be limited by the open hole 325. This prevents the insertion member 331 from unintentionally dropping from the mounting surface 322a before the insertion member 331 is inserted into the insertion hole 324, thereby preventing the upper support base 33 and the car shock absorber 21 from falling down. Can do. Therefore, the labor for adjusting the height position of the car shock absorber 21 can be further reduced.

  Further, the shape of the opening of the insertion hole 324 when viewed along the depth direction of the insertion hole 324 is square, and is along the direction in which the insertion hole 324 is inserted (that is, the axial direction of the insertion member 331). Since the outer shape of the insertion member 331 is a square that matches the shape of the opening of the insertion hole 324, the horizontal angle of the insertion member 331 is adjusted with respect to the opening of the insertion hole 324. The corner portion of the outer shape of the insertion member 331 can be placed on the mounting surface 322a, or the insertion member 331 can be inserted into the insertion hole 324. Thereby, it is possible to further reduce the labor for adjusting the height position of the car shock absorber 21.

  Further, since the insertion member 331 is held on the lower support base 32 by the holder 34 while being placed on the placement surface 322a, the insertion member 331 is prevented from unintentionally moving on the placement surface 322a. The insertion member 331 can be moved only when the height of the shock absorber support device 31 is adjusted.

  In addition, the holder 34 has an insertion plate 341 inserted into the slit 335 of the insertion member 331 and a holding bolt 342 that fastens the insertion plate 341 and the fixing plate 323 of the lower support base 332. The state where the insertion member 331 is placed on the surface 322a can be held with a simple configuration.

  In the above example, the shape of the opening of the insertion hole 324 is square. However, the shape is not limited to this, and any shape other than a circle may be used. The shape of the opening of the insertion hole 324 may be, for example, a polygon other than a square or an ellipse. Further, if the shape of the opening of the insertion hole 324 is a regular polygon and the outer cross-sectional shape of the insertion member 331 is a regular polygon according to the shape of the opening of the insertion hole 324, the corner of the outer shape of the insertion member 331 is obtained. Can be stably mounted on the mounting surface 322a.

  In the above example, the outer cross-sectional shape of the insertion member 331 is a shape that matches the shape of the opening of the insertion hole 324, but the present invention is not limited to this. For example, the shape of the opening of the insertion hole 324 may be a rectangle, and the outer cross-sectional shape of the insertion member 331 may be an ellipse.

  Further, in the above example, the outer cross-sectional shape of the housing member 322 is a square, but may be a shape other than a square, for example, a polygon other than a square, an ellipse, or a circle.

  In the above example, the cross-sectional shape in the insertion hole 324 and the shape of the opening of the insertion hole 324 are the same, but a part of the opening of the insertion hole 324 is closed with a plate, and the insertion hole 324 is closed. The shape of the opening may be different from the cross-sectional shape in the insertion hole 324. In this case, the outer cross-sectional shape of the insertion member 331 is set to be insertable into the opening of the insertion hole 324.

  In the above example, a square pipe is used as the insertion member 331. However, for example, a rod-shaped member or a block may be used as the insertion member 331. Furthermore, in the above example, a square pipe is used as the housing member 322. However, for example, a block provided with an insertion hole 324 may be used as the housing member 322.

  In the above example, the fixed plate 323 which is a plate-like member is used as the fixed member fixed to the mounting surface 322a of the housing member 322. However, the cylindrical member in which the open hole 325 is formed is used. It may be used as a fixing member. In this way, the insertion member 331 placed on the placement surface 322a can be surrounded by the inner peripheral surface of the opening hole 325, and the insertion member 331 placed on the placement surface 322a can be made difficult to fall.

  In the above example, the housing member 322 and the fixing plate 323 are separate members, but the housing member 322 and the fixing plate 323 may be formed of a single material.

  In the above example, the present invention is applied to an elevator in which a plurality of car entrances 7 and 8 are provided in the car 6. However, the present invention is applied to an elevator in which one car entrance is provided in the car 6. You may apply.

  In the above example, the present invention is applied to the shock absorber support device 31 that supports the car shock absorber 21.
